ac inprofi 'io loosely :2- o pin; 19 and counter bo -e ii Thereof adapted 20 and being- :nremied the shank 21 I coopoi' t' i such tho; Um oiungw and o oo the lateral opening to rotate independently of the connected together collar 10 and the cap 18, it will be apparent that the body 1 can turn to, engage the nozzle portion 3 of the barrel with threaded filler openings of lubricant receptacles without there being any necessity of moving the lever 16, which might be impracticable in instances on account of the space required therefor. The body of the barrel 1 is preferably providedwith an enlargement 26. at its upper end whichis formed'with a plurality of faces 27 which are adapted to be gripped by a wrench or like tool to efi'ect the adjustment of the barrel with respect to an oil cup or receptacle, if required. a

When 'thebarrel 1 has been applied to a receptacle in the .m'anner described, the lever 16 is swung upward until the lower end of. the .plunger 19 is positioned above 25 through the body of the'barrel. A quantity of a relatively hard lubricant, which in the service for which used in connectionwith the lubrication ofcrank pins and like moving parts of a locomotive engine is a grease having the consistency of hard yellow laundry soap, is introduced through the opening 25 into I the barrel until the bore or chamber thereof is filled to the-level of the opening 25.

A ressure isthen appliedto the lever'16 and the plunger 19 is moved downward, thereby forcing the relatively hard lubricant through the reduced passage 8 into. the oil cup or receptacle. The dotted lines in Figure 1 indicate the position from which the plunger 19 will be moved relatively to thebarrel 1 to elfect the forcing of a lubricant disposed in the barrel through the nozzle 3 into the receptacle with which the nozzle is connected at its lower end.

The device is simple in construction and can be readily applied and operated.

Obviously myirivention is susceptible of embodiment in forms other than that illustrated in the accompanying drawings and I therefore consider as my own allmodifica- I tions of the forms of the device herein disclosed, which fall within the scope of. the ap ended claims.

Iaving whait I claim is L-A lubricant gun comprising a barrel having a nozzle at one end adapted for connection with a lubricant receptacle and having a lateral opening formed through its Walls at an appreciable distance from the inner end of the nozzle portion the bore of said barrel being reduced diametrically to. define an annular shoulder at the inner end of the nozzle portion and to provide a'reduced passage through the nozzle portion, a plunger movable in the barrel from the end thereof remote from the nozzle portion past the lateral opening into abutting relation at its end with the said shoulder, a collar 'rotatably mounted upon the barrel adjacent to the nozzle portion thereof, a cap rotatably mounted upon the plunger at the end thereof remote from the nozzle portion of the barrel, and a lever and link arrangementconnecting the collar and the cap for reciprocating the plunger inthe barrel.

2. A lubricant gun comprising a barrel having a nozzle at one end adapted for connection with a lubricant receptacle and having a lateral opening formed through its walls at an appreciable distance from the inner end of the nozzle-portion, the bore of said barrel being reduced diametrically to define an annular shoulder at the inner end of the nozzleportion and to provide a reduced'passage through the nozzle portioin' a plunger movable in the barrel from the end thereof remote from the nozzle portion past the lateral opening into abutting relation at its end with the said shoulder.
